摘要:I examine some properties of the overlap operator in the Schroedinger functional formulated by
Lüscher at perturbative level. By investigating spectra of the free operator and one-loop coefcient
of the Schroedinger functional coupling, I conrm the universality at tree and one-loop level.
Furthermore, I address cutoff effects of the step scaling function and it turns out that the lattice
artifacts for the overlap operator are comparable with those of the clover action.
